Hundreds of German politicians, including Chancellor Angela Merkel, have had personal details stolen and published online.
Contacts, private chats and financial details were put out on Twitter which belong to figures from every political party except the far-right AfD.
Data from celebrities and journalists were also leaked.
It is unclear who was behind the attack, which emerged on Twitter in the style of an advent calendar last month.
